DESCRIPTION AND EVALUATION OF A SIMPLIFIED METHOD TO ACHIEVE PASSIVE FIT BETWEEN CAST TITANIUM FRAMEWORKS AND IMPLANTS

Because osseointegrated implants have no resilience in bone, passive f it between dental implants and prosthetic superstructures has been ide ntified, both from biologic and mechanical perspectives, as a potentia l discriminating prognostic factor Distortion of the metal framework d uring the casting procedure has been cited as a main cause of misfit. The objectives of the present article were to describe a recently pres ented method (CrescoTi Precision method) intended to correct for disto rtion in cast titanium frameworks, and to elucidate and evaluate the m ethod by photoelastic and strain gauge techniques. The method appears to be an efficient and accurate procedure for correcting for distortio n in cast titanium frameworks.
